The bottom line No known interaction

We found no known interaction between Cashew and Amphetamine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Interaction report

Cashew and Amphetamine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Amphetamine and Cashew in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Cashew safety at a glance

Cashew overall Generally safe Cashews are safe as a food for most people, but those with tree nut allergies must avoid them.
Pregnancy Use caution Cashews are generally fine as a food in pregnancy, but concentrated supplements or extracts have not been well studied.
Breastfeeding Use caution Eating cashews as food is usually fine, but supplement-strength products lack safety data while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Amphetamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amphetamine is filed under 6 classifications — including monoamine oxidase inhibitors (maois), amphetamines, stimulant drugs. Cashew has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Amphetamine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

What to actually watch for

What Cashew Itself Has Been Linked To

This is not an interaction — nothing below involves Amphetamine. It is the side-effect record for Cashew on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Cashew, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Wheezing / Shortness of breath / Hives Worth acting on Additional detail

    “Orally, there are numerous reports of cashew nut allergy. Symptoms have included asthma, hives, swelling, wheezing, gastrointestinal symptoms, and shortness of breath.

    Topically, contact with cashew can lead to redness and nodule and blister formation. Alkyl phenols contained in the cashew nut shell are strong skin irritants, similar to alkyl phenols found in poison ivy, poison oak, mango, and ginkgo.”

  • Weight gain Additional detail

    “Orally, cashew nuts may cause constipation, bloating, weight gain, fatigue and feelings of malaise, or worsening joint pain in some patients, but these side effects are rare. Very large intakes of the cashew nut or pseudofruit have resulted in oxalate nephropathy in case reports.

    Orally and topically, cashew nut can cause allergic responses in some patients.”

Overlapping uses

What Amphetamine Is Prescribed For, and What Cashew Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Amphetamine is a prescription medicine with approved uses on its FDA label. Cashew is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Amphetamine is prescribed for: Amphetamine treats Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older. Adzenys XR-ODT, Dyanavel XR, and the amphetamine extended-release orally disintegrating tablet formulations are specifically approved for ADHD in this age group. Amphetamine Sulfate tablets and Evekeo (amphetamine sulfate tablets) are also approved for narcolepsy (a sleep disorder causing uncontrollable daytime sleepiness) and as a short-term aid in a calorie-restricted weight-loss program for exogenous obesity (weight gain from external factors like overeating) in patients who have not responded to other approaches.

Cashew has been studied for:

  • Obesity studied, not established Cashew has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Cashew for obesity

    A small clinical study in patients with overweight to severe obesity shows that consumption of a shake containing cashew nuts 30 grams and Brazil nuts 15 grams in the morning following an overnight fast has no effect on subjective appetite sensations, food intake at lunch, or energy intake throughout the day when compared with an isocaloric control shake without nuts.

    1 source cited
    1. 106925. Costa MAC, Hermsdorff HHM, Caldas APS, et al. Acute consumption of a shake containing cashew and Brazil nuts did not affect appetite in overweight subjects: a randomized, cross-over study. Eur J Nutr 2021;60(8):4321-4330. PubMed

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Amphetamine on your own; if you are taking Cashew for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Cashew

What is Cashew?

Cashew
  • Heart health support
  • Source of protein and minerals
  • Blood sugar support
  • Traditional digestive remedy
  • Skin and oral care (traditional)

Cashews are a nutritious tree nut that provides protein, healthy fats, fiber, and minerals like magnesium and copper. Eaten as part of a balanced diet, they may support heart health, but evidence for cashew supplements treating any specific disease is limited. People with tree nut allergies must avoid them entirely.

Anacardium occidentale · Anacardiaceae · Nut (seed), nut shell oil, leaves, and bark · Whole nuts, cashew butter, cashew milk, oil, and capsules or extracts

An interaction check asks whether these two react with each other — it does not ask whether Cashew is a good idea for someone in your situation. Here is what our Cashew record says about it on its own.

Cashew: dosing

There is no standardized medicinal dose for cashews. As a food, a typical serving is a small handful of nuts, similar to other nuts. They can be part of a balanced diet for most people.For cashew capsules, extracts, or oils, follow the directions on the product label, since amounts vary by product.

Taking Cashew and Amphetamine Together: Common Questions

Is it safe to take Cashew with Amphetamine?
We do not list a known interaction between Cashew and Amphetamine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Are Cashew and Amphetamine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Cashew in each. That is a conversation for your prescriber, especially if Amphetamine is being adjusted to a target.
How was the Cashew and Amphetamine combination checked?
Interactions in our licensed database are recorded against drug classes. Amphetamine is filed under 6 classifications, and Cashew has documented interactions with 1 drug class — none of Amphetamine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Cashew interact with any other medications?
Yes. Cashew has 86 documented drug interactions in our database — Amphetamine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Amphetamine interact with any supplements?
Yes. Amphetamine has documented interactions with 130 supplements in our database — Cashew is not one of them. The Amphetamine interaction page linked on this page lists every one, ranked by severity.
